What is the best way to maintain the resale value of a Nissan X-Trail?

I am planning to sell my Nissan X-Trail in a few years and want to make sure I get the best resale value possible. What should I do to maintain the value of my car?

Regularly service your car at an authorized Nissan service center to keep it in top condition.

Keep complete documentation of your car's maintenance and repairs to show potential buyers.
